"We prepare for the winter by making sure all the cars have the correct tires, making sure that everything's working on the cars. We talk to the driver and make sure that they understand what cautious driving means," said Herrick.

For people who have to man the roads in the bad weather, it's not just the snowplow drivers that can give some good advice: "Don't follow too closely, don't accelerate too quickly, don't stop too quickly. Use your momentum carefully. Your car will go in the direction you point it for a little while. You just got to keep it on the same path, keep it on the good path," said Herrick.

Maybe, just maybe, braving the storm has its perks. "The fact that you're up and running gets you customers in the long run," Herrick said.

He said Green Cab VT's never stopped running because of a storm. Herrick attributes part of that to the Agency of Transportation for helping to keep the main roads clean.

Herrick also said that revenue tends to be lower when it snows, but tips are higher.
